Do what they will, then, we remain
conscious of a desire which no natural
happiness will satisfy. But is there any reason to suppose that reality offers any satisfaction to it? “Nor does the being hungry prove that we have bread.” But I think it may be urged that this misses the point. A man’s physical hunger does not prove that that man will get any bread; he may die of starvation on a raft in the Atlantic. But surely a man’s hunger does prove that he comes of a race which repairs its body by eating and inhabits a world where eatable substances exist.
